Hi all, I have these wheels but I'm not sure the tyre spec for them. The outside of the bead dia is approx 640mm (bit hard to measure with the wheels built) Rim width is 30mm. A 27 x 1/4 fits but pops off the bead under a bit of pressure, a 700 tubular fits nicely but of course the width is too narrow. I don't even know if this is a tubular or a clincher rim, the other style of woods I have are clinchers with a 28 x 1 3/8 tyres. Any ideas?

You can get bigger sizes in tubulars that are used in cyclocross and (in the past at least) for racing across rough pave. Cyclocross tubs used to available upto 700x35c. Also, folk used to race 'The Hell of the North' on 28c and above tubulars. Check the internet, I doubt you'll find any in Australia.

They look like clincher rims to me. Wood tubular rims don't have a well. If 27" pops off, the next size down is 700c clincher. I have never seen a 27 X 1 1/4 wood clincher rim, but have seen them or built them in 24 X 1 3/8, (wheelchair), 26x 1 3/8, 28 X 1 3/8, 28x 1 3/4 (same as 700c). Could you try a 700 X 35 clincher tyre on them?

Ummm that all depends on the type of wood used, but they are still being made, with disc brakes you can now get 29er rims if you are really keen. After a really wet and muddy ride just need to...Maintaining the precious wooden rims is very easy. GHISALLO uses special coatings from boat building for the painting. I maintain the wooden rims with “Homemade Furniture Polish”! This is olive oil with a splash of white wine vinegar. Have a look at the small glass in the Picture. It must be applied with a soft cloth. After an hour I wipe off the rest and the wooden rims are ready for the next race.>By the way, I care for bamboo rims with turpentine.

Well big $$ can be made in the resto and L'Eroica world. I had a very close look at some 1950s track wheels with timber tub rims in the LBS a few years back when I was building up my ss 29er so that is how I knew about this lot. I did think long and hard about giving a set a run but the price for the phil hubs used blew out my budget. The wheels had been hanging in the shop wall for as long as I could recall and still had the odd spoke reset to keep them round but they were past the days of being able to ride them as they went brittle on the edges. Could have been because of the old glue they did use back in the day must have been quite harsh and dried out the wood? The new types of glues or the clincher rims they sell should have a pretty long life if you looked after them.
